Patented Feb. 20, 190e,

To all whom it may concern:

Be it known that I, WIL IAMC. ALLEN, a

'citizen of the United States, residing at Gur- Madison, State of Ala and useful Improvements in Pneumatic Grain-Elevators;' and I do hereby declare the following ley, in the county of to be a full, clear, and exact description of skilled in the art to which it appertains to With these and other objects in viewthe present invention consistsin the combination and arrangement of parts, as will be hereinafter-moreful1 described, shown in the accompanying diawings, and particu in the appended claims, it being understood that changes made within the scope of the appended claims without departing from the spirit or sacrificing any of t e advantages of the. present invention.

In the drawings, Figure 1 'is'a view illustrating my invention partly. in perspective and partly in section. Fig. 2 is a detailview of the baffle-plate, illustrating its connections for adjusting the same.

Referring now more particularly to the ac} companying drawings, the reference character '1 designates a vacuum-chamber having an opening 2 in its front and at the bottom thereof, over which, as at 3, is hingedly con.-

nected a door or closure 4, there being) a platform 5 extending outwardlytfr'om eneath.

Connected to one side of the vacuumchamber 1, through an opening therein, is a vessel, bin, or the like,

horizontal elevator pipe or tublng 6, having an elbow '7,'to which the vertical eonvefer pipe or tubingS is connected, the latter emg disposedover the grain within the car, as is Well understood. For the urpose of illustration-I'h'ave illustrated a in 9 into which the lower end of the pipe ortubing8 projects. Connectedthrou h another opening in the opposite side of t e in the form, thereof.

proportion, size, and minor details may be' of the 'va'ouum-chamber.

aforesaid opening is formed is another openplpe 1() which leads to an opening 11 in one side of the fan-casing 12, in which latter is mounted a shaft 13, having one end 'jour naled in the upper endof the bracket 14, whose feet 15 are pierced by a spike or other suitable element 1:6 for securing the bracket upon the platform 18, upon which latter the fan-casing is also secured, as clearly shown vacuum-chamber from that in which the mg, into which is fitted a second horizontal in the draw'm s. l The shaft 13 has a pulleywheel 19fixe y secured thereupon, to which may be connected a belt, (not shown,) whereby the fan may be driven for a purpose hereinafter explained. It Will'be observed that the platform 18 is supported upon legs 20,

which are connected by the cross braces 21, whereby the platform may be held rigidly against accidental displacement by reason of the, motion of the fan-motor.. f

Depending from the under face of the top 22 of the vacuum-chamber, 1 andfixedly'secured thereto in any suitable'nianneris an arched'bafiie-plate 23, whose lower free end 23 is turnedbackwardly toward the latter end ofthe baffle-plate is arranged substantially on a'line with the bottom of the pipe I -1 6 the baflie plate be ing constructed and arranged in a manner stated for the purpose It will be observed that the lower of preventing the grain being thrown directly 1 over the pipe 6 into the pipe 10 and directing the grain downwardly toward the bottom 23-iscomposed'of spring material, so that its lower end may be raised and lowered by a lift.

or push upon the cross-piece 24 at the u per ends of the spacedparallel arms 25,"w ose lower ends are connected to the correspond- I ing side edges of the bafiie-plate 23. A

om the foregoingit will be understoo that when the fan is set. in motion a vacuum is created in chamber 1, causing the grain to be thrown upwardly through the pipes'8 and 6 thereinto, and it will be appreciated that if it were not forthe baffle-plate 23 the grain would have a tendency to be thrown overthe,

upper portion of the vacuum-chamber linto the pipe 10;,but b reason of the baflie-plate the grain is cause to fall toward the bottom of the vacuum-chamber, where it may be removed, if desired, through the opening 2,

alls

closed by the door 4. Now as the grain to the bottom'of the vacuum-chamberthe fan, through suction, causes the light subioo 15 a acuum-chamber, a feed-tubing connected stance from the grain to be drawn through thepipe 10 into the fan 12, throughwhich, latter it may drop through the opening-26- into the pipe 27, fitted through an opening 28 in the platform 18 and communicating yvith an Opening in the bottom of the fan-casing. I a

In the use of my apparatus the ain is elevated and cleaned" simultaneous y, the cleanings or light substance being conveyed through the 'fan and thepipe 27 to a suitable receptacle (not shown) in a manner now ell understood. i

What is claimed is 1. In an apparatus of the class described,

therewith, a rotary fan, connections between- I the fan and the vacuum-chamber, means for Y rotating the fan, a discharge-tube arranged 2. In an apparatus of the class described, a Vacuum-chamber, a rotary fan, connections between the fan and the Vacuum-chamber,

means for rotating the fan,-a discharge-tube arranged beneath the fan,'a baffle plate composed of spring metal and secured to the top of the vacuumchamber, and spaced arms connected at'the top by a crossiece and at the bottom to the-lower edge 0 to adjust the said baffle-plate. v

In testimony whereof I afiix my signature in presence of two witnesses' 1 Y WILLIAM C. ELLEN. Witnesses: z v i H. Y. ONEAL, J. E. KNIGHT.
